Dell Computer Duel display won't work

[CochrellGary]

Just thinking out loud but if you are feeding s-video to an rf modulator doesn't that imply an rf signal is comming out of your modulator (ch 3 or 4)? That means you need a 72 ohm coax to your TV. A yellow cable implies just a shielded cable with an RCA connector. I am using the Radio Shack modulator as my example.

You can totally ignore this post if your modulator also outputs a RCA connector type video signal along with a modulated RF signal.

Again, just thinking out loud.
